[0035] The isolation plate 4 is located outside the strong current interface 2 and the weak current interface 3 .

[0036] The strong current interface 2 and the weak current interface 3 are distributed longitudinally, and the isolation plate 4 is movably arranged on the cup body 1 up and down.

[0037] A weak current opening 5 is provided on the isolation plate 4 . When the isolation plate 4 moves (moves downward) to the third position A, the weak current opening 5 faces the weak current interface 3 to open the weak current interface 3 .

[0038] The cup body 1 is provided with a first opening 6 facing the high-voltage interface 2 . When the isolation plate 4 moves (moves upward) to the second position B, the first opening 6 is opened to open the high-voltage interface 2 .

[0039] The cup body 1 is provided with a second opening 20 facing the weak current interface 3 . When the isolation plate 4 moves (moves downward) to the third position A, the weak current opening 5 faces the second opening 20 .

[0040] A guide groove 7 is provided on the cup body 1, and a guide edge 8 is provided on the isolation plate 4. The isolation plate 4 is guided (slid) up and down on the cup body 1 through the cooperation of the guide edge 8 and the guide groove 7. The guide groove 7 can limit the isolation plate 4 front, back, left and right, so that the isolation plate 4 can only move up and down.

[0041] The cup body 1 is provided with a first limiting portion 9 and a second limiting portion 10 arranged upper and lower, and a limiting rib 11 is provided on the isolation plate 4. When the isolation plate 4 moves upward to the second position state B, the limiting rib 11 acts on the first limiting portion 9, and when the isolation plate 4 moves downward to the third position state A, the bottom of the isolation plate 4 acts on the second limiting portion 10, so that the isolation plate 4 can accurately reach the second position B when it moves upward and can accurately reach the first position A when it moves downward.

[0042] A notch 12 is provided on the side of the cup body 1, and the isolation plate 4 is movably provided on the notch 12 up and down. An inner cavity 13 connected to the notch 12 is provided inside the cup body 1, and the isolation plate 4 extends into the inner cavity 13 when it moves upward; an operating part 19 for moving the isolation plate 4 is provided on the isolation plate 4, and the operating part 19 is a convex rib and has the same structure as the limiting rib 11. The isolation plate 4 can be pushed upward or pulled downward by hand through the operating part 19.

[0043] A cover plate 14 is provided on the slot 12, and the cover plate 14 is located on the outside of the isolation plate 4. A disassembly and installation portion is provided between the cover plate 14 and the cup body 1, and the cover plate 14 is installed on the slot 12 through the disassembly and installation portion. When the high-voltage interface 2 or the low-voltage interface 3 needs to be used, the cover plate 14 must be removed from the slot 12 first, and the isolation plate 4 can only be moved after the cover plate 14 is removed; when the high-voltage interface 2 and the low-voltage interface 3 are not in use, the cover plate 14 can be covered to protect the high-voltage interface 2 and the low-voltage interface 3.

[0044] The cover 14 is made of a soft material such as silicone or rubber, and plays a role in protecting the high-voltage interface 2 and the low-voltage interface 3 . The slot 12 can be closed when not in use.

[0045] The first limiting portion 9 is disposed at the top of the notch 12 , and the second limiting portion 10 is disposed at the bottom of the notch 12 .

[0046] The disassembly and installation part includes a mounting post 21, a limiting block 22 and a limiting matching block 23 and a limiting groove 24 provided on the cover plate 16. The limiting block 22 is provided at one end of the mounting post 21, and the limiting groove 24 is provided on the limiting matching block 23. A third limiting portion 25 is provided on the bottom cover 16 at the bottom position of the notch 12; the mounting post 21 is inserted into the limiting groove 24, and the limiting block 22 is pressed outward against the limiting matching block 23, the upper end of the cover plate 14 is pressed against the first limiting portion 9, and the lower end of the cover plate 14 is pressed against the third limiting portion 25, so that the cover plate 14 can be fixed on the notch 12. An acting portion 26 is provided, and the cover plate 14 is a soft rubber. When the cover plate 14 is disassembled, the cover plate 14 is pulled outward by the acting portion 26. Since the cover plate 14 can be deformed, the upper end of the cover plate 14 can move outward, thereby breaking away from the restriction of the first limiting portion 9. Then the cover plate 14 can be lifted upward, so that the mounting column 21 breaks away from the limiting groove 24, and then the limiting block 22 breaks away from the restriction of the limiting matching block 23. At this time, the cover plate 14 can be pulled outward from the notch 12 to realize the disassembly of the cover plate 14; the principle of installation of the cover plate 14 is the same as that of disassembly, both of which utilize the deformation of the cover plate 14, but the process is reversed, which will not be described in detail here.

When disassembling, you only need to pull the bottom cover 16 out of the cup body 15 to disengage the clamping rib 27 from the bayonet 28; after the cup body 15 and the bottom cover 16 are disassembled from each other, the isolation plate 4 can be taken out; when installing the cup body 15 and the bottom cover 16, first install the isolation plate 4 to the first limit groove 17, and then install the bottom cover 16 to the bottom of the cup body 15.

[0049] A bracket assembly is provided at the bottom of the cup body 1, and a second disassembly connection portion is provided between the bracket assembly and the bottom cover 16.
